Valley current mode pulse train control technique for switching DC-DC converters

To eliminate the low-frequency oscillation phenomenon in pulse train controlled switching DC-DC converters operating in continuous conduction mode (CCM), a valley current mode pulse train control technique is proposed. The experimental results show that by using the proposed control technique, the low-frequency oscillation in the pulse train (PT) controlled CCM switching DC-DC converter can be eliminated, while the great robustness and excellent transient performance of the traditional PT control technique can be retained.
